☼ Shining Loop ☾

---- RULES ----
Normal Sudoku rules apply: Fill the grid with digits 1 to 9 appearing once each in every row, column, and 3x3 box.
Moon-or-Sun Loop: Draw a single non-intersecting loop into the grid by connecting centers of orthogonally adjacent cells. The loop must fulfill the following rules:
- The loop enters every cage exactly once.
- Within a cage, the loop only passes through cells of the same parity while when the loop crosses cage borders, the parity of the loop switches.
- Within each cage, the loop must pass through at least one moon or sun.
Killer Cages: Digits within cages cannot repeat, and they must sum to the small number (if given).

Thanks for these. Lots of enjoyment working through the six (so far) puzzles in the last couple of days. Every one of them was excellent with such a good range of different challenges and variants along the way.

Very nice loop building aided by coloring parity, and just enough information with the cage totals to disambiguate all values. Very fun puzzle!

It is a wonderful, wonderful puzzle! It is not very hard and very very smooth provided one doesn’t lose sight of the rules. Beautiful deductions all along the way.
